Abstract
An eight-channel hybrid-integrated light source with 100 GHz channel spacing fabricated by a passive alignment technology is demonstrated. Side mode suppression ratios of better than 40 dB were obtained via grating couplers under eight-channel simultaneous operation at a continuous wave current of 600 mA and 25°C. The surface slotted laser array fabricated by standard lithography butt-joint with silicon photonic devices was demonstrated for the first time, to the best of the authors’ knowledge.
